Archimedes was an ancient Greek mathematician and inventor. He made mathematical discoveries as he solved everyday problems. He invented machines to move heavy objects, carry water, and fight battles. Archimedes recorded his discoveries so that others could learn from them. Today he is considered one of the greatest mathematicians of all time.
Archimedes was born in the Greek city-state of Syracuse, Sicily, in 287 bc. His father, Phidias, was an astronomer. Archimedes also studied astronomy.
It is believed that Archimedes visited the famous library of Alexandria, Egypt, where he met great scholars. While in Egypt, he is said to have invented a machine to carry water upward from one level to another. The machine, known as Archimedes’ screw, is still used in parts of the world today.After studying in Alexandria, Archimedes returned to Syracuse. He wrote many works to explain his discoveries. Archimedes’ most-famous ideas include his explanations of how levers and pulleys can lift and move heavy objects. Another idea, called Archimedes’ principle, is a scientific law. It describes what happens when an object floats in water.
In 213 bc Romans attacked Syracuse. Archimedes invented machines to defend the city. When Syracuse was finally overtaken, Archimedes was killed there in 212 bc.
The above-mentioned method is used to analyze the streak of a mineral. Streak can be different from that of the color of the mineral, itself. It is used for soft minerals, and such minerals have their characteristic streaks. So the correct answer to your question is D.
If i cut my finger, <u>mitotic division</u><u> in the finger cells</u> helps me heal and ensures that my skin type is the same.
- We are able to expand, recover from injuries, and replace damaged cells because of mitosis.
- Since this is the only method that these cells can replicate, mitosis is also crucial in creatures that reproduce asexually.
- This is the one essential mechanism that keeps asexual creature populations alive.
- It is widely known that an open (incised) skin wound that penetrates the epidermis and into the dermis beneath causes an abnormally quick spike in the epidermal mitotic rate within 24 hours.
- The highest rate of mitosis occurs in cells that are closest to the edge of the wound, and the lowest rate is close to the usual rate, or approximately 1 mm.
